They look like Rhoms, i just got one with a lot of yellow on like yours but is a bit bigger and Darker.
Your pics are not quite adequate for a 100% positive id.
But especially in the last pic I see the spots showing an compressus -like alignment.
This is, on it's own, not enough to state that it's a compressus-group member. It also looks a bit elongated.
A new morpho-type of, probably, S. rhombeus has started to appear in the hobby, it may be on of those.
For any certainty in ID. origin is always important.

They look indeed like a rhombs. But the origin would help a lot.
If you can find out, that is.
I got mine from a Brassilien shipment, but some of them have some peruvian features. So nothing can be said 'till time has told the truth.
But try track down the origin the best you can, and I may be able to tell you more.

Hey dudes i askt the guy i bought them from the zooztore he said they are wild cought and from brasill ,.,.its kinda strange the other one is kinda darker and started showing litle reed on the eyes .,.but not the big one so i wonder if it is 2 different species., the 4th one the picture that is the other one ,,but u cant c it in the picture he is allot darker.,.in real life i mean if u look .,but the bigger one is more aggresive ,.,and when the lights r down they attack me as soon as i move my finger ,,.but not with the lights on..?? help me dudes,.,respekt
In many ways I would definately say your fish are members of the rhombeus-complex.
To help you get around that term, you should not regard "s. rhombeus" as a specific specie, but as a complex of closely related species.
F.ex. the pride of my collection does in most ways show the features that differ S. rhombeus from the other species in Serrasalmus, but it also shows features that are not holotype rhombeus-like.
So taxonomically it's not a S. rhombeus, 'till further notice, but definately a complex-specie.
So, if you want your fish to be Serrasalmus rhombeus, then they are for now, at least 'till dr. Michel Jégu has come up with some results on his work on the venezuelean variations. Results that may help us understand the morphological variations from the Amazon as well.
